Description

With a simple motion, a jack-in-the-box-like spring designed at NASA’s Jet Propulsion Laboratory showed the potential of additive manufacturing, also known as 3D printing, to cut costs and complexity for futuristic space antennas. Called JPL Additive Compliant Canister (JACC), the spring deployed on the small commercial spacecraft Proteus Space’s Mercury One on Feb. 3, 2026. An onboard camera captured this video of the spring popping out of its container as the spacecraft passed over the Pacific Ocean in low Earth orbit.

Figure A is a still image of JACC after deployment, taken above Antarctica.

JACC is one of two JPL payloads on the spacecraft that are demonstrating new technologies designed to take up reduced volume while precisely deploying antennas on future orbiters. JACC’s success demonstrates that 3D-printed mechanisms can be built faster, cheaper, and with less complexity than traditionally fabricated space hardware. 

Printed out of titanium, JACC uses three times fewer parts than similar structures: Combined into a single part is a hinge, panel, compression spring, and two torsion springs. Weighing just over 1 pound (498 grams), it is about 4 inches (10 centimeters) on each side. The spring, which extends from a packed height of just over 1 inch to about 6 inches (3 centimeters to 15 centimeters), is modeled after communication antennas commonly used on satellites. 

The second demonstration payload aboard Mercury One is the Solid Underconstrained Multi-Frequency (SUM) Deployable Antenna for Earth Science. Together with JACC, the two payloads go by the name Prototype Actuated Nonlinear Deployables Offering Repeatable Accuracy Stowed on a Box (PANDORASBox). They were both conceived, built, tested, and delivered for flight by JPL in less than one year on minimal budgets.

Mercury One launched from Vandenberg Space Force Base in California on Nov. 28, 2025, as part of SpaceX’s Transporter-15 mission.

JPL internal research development funds supported JACC, as did NASA’s Earth Science Technology Office (ESTO).

For over 50 years, the Landsat program has provided the longest continuous satellite record of Earth’s land surface from space. Landsat 9, launched in 2021, is the latest mission in this remarkable legacy — building on decades of Earth observation with upgraded technology, including enhanced radiometric resolution, improved signal-to-noise performance, and polar night thermal imaging. Working in tandem with Landsat 8 to map the entire planet every eight days, Landsat 9’s data is being fused with the European Space Agency’s Sentinel-2 satellites to enable near-daily global observations, delivering sharper, more detailed observations that help scientists and communities monitor a changing planet.

VIDEO SCRIPT

It started over 50 years ago with an idea:
 
A satellite, orbiting Earth, observing our planet’s surface, gathering data, day in, day out.
 
That idea gave birth to the Landsat program, a partnership between NASA and the US Geological Survey, the longest continuous record of Earth’s land surface from space.
 
Landsat 1’s launch in 1972 was the first link in a chain of 8 satellites, each one building upon the last.
 
And today, Landsat 9 carries that legacy forward.
 
Since its launch in 2021, Landsat 9 helping collect more scenes per day than any previous Landsat satellite mission. collects as many scenes per day as Landsats 5 & 7 combined.
 
Working in tandem with Landsat 8, the pair now collect nearly 1,500 scenes daily, creating a complete map of the planet’s land surface every 8 days.
 
It’s not just about scale — it’s about Landsat’s ability to revisit the same scene multiple times a month. With this pace of acquisitions, Landsat 9 helps track seasonal shifts in crops, the spread of wildfires, the aftermath of storms, and even rapid changes in glaciers and coastlines.
 
More images mean more data, fueling research and scientific applications around the world.
 
But when it comes to Landsat 9’s imagery, it’s not just about quantity – it’s about quality too.
 
While Landsat 9’s main design is nearly identical to Landsat 8’s, it’s able to collect data in greater detail thanks to an upgraded radiometric resolution — 14-bit instead of Landsat 8’s 12-bit.
 
Think of it like upgrading from a box of 4,000 crayons to one with 16,000 — every shade captured, every subtle detail sharper.
 
Landsat 9’s quadrupled radiometric sensitivity makes a real difference when capturing data over the planet’s brightest surfaces, like snow and ice, revealing subtle changes that might otherwise go unnoticed: shifts in ice extent, changes in how surfaces reflect sunlight, even the growth of glacial lakes forming where ice once stood.
 
Seeing more shades of detail is powerful, but it only matters if the picture itself is clear.
 
Landsat 9 not only sharpens what we can detect, it also cuts through the static, delivering a stronger signal-to-noise ratio, which means images that have less interference. 
 
It’s like trying to hear a whisper in a noisy room — Landsat 9 quiets the static so we don’t miss anything important.
 
And that clarity makes a difference, especially over dark surfaces like water which can harbor harmful algal blooms that can spread quickly, threatening drinking water supplies, local wildlife and even human safety.
 
By spotting these blooms with greater sensitivity, Landsat 9 gives communities and scientists more reliable and actionable information to respond.
 
Landsat 9 doesn’t clock out when the sun goes down – its onboard thermal sensor, TIRS, measures our planet’s surface heat even in darkness.
 
That means we can monitor urban heat islands, volcanic hotspots, and water temperature at night.
 
Since 2022, the US Geological Survey’s special request data program has implemented the Landsat Extended Acquisition of the Poles, or LEAP for short, taking advantage of Landsat 9’s ability to see in the dark to acquire imagery in polar regions year-round when the sun can set for up to six months at the poles.
 
Together with Landsat 8, the satellites can detect features like meltwater, cracks, and even open water within ice under low light conditions.
 
The enhanced coverage helps scientists better monitor ice dynamics and seasonal changes in polar regions, detecting calving events, surface melt, and changes in sea ice extent even during the dark months.
 
Landsat 9 isn’t working alone — it’s part of a global team of satellites, where collaboration across agencies and nations is giving us the clearest, most consistent view of Earth yet.
 
NASA’s Harmonized Landsat Sentinel-2 project fuses data from Landsats 8 & 9 with that of the European Space Agency’s Sentinel-2 A,B and C satellites to form a seamless, consistent surface reflectance record.
 
In this “virtual constellation,” Landsat 9 contributes its spectral precision and calibrated data, helping enable global observations every 1-2 days at 30-meter resolution.
 
Landsat 9’s high fidelity, radiometric stability, and continuity anchor HLS, ensuring that the fused product maintains the scientific integrity that Landsat users expect.
 
Landsat 9 is more than just today’s mission — it’s part of the foundation for the future.
 
Through the Sustainable Land Imaging program, NASA and the U.S. Geological Survey aims to preserve our ability to keep a continuous, reliable record of Earth’s land for decades to come.
 
That means not just flying satellites, but building the technology, partnerships, and planning needed to keep the record unbroken.
 
Within SLI, NASA’s Sustainable Land Imaging–Technology initiative is testing new instruments that could make future missions smaller, more capable, and more efficient.
 
Landsat 9 is NASA’s first SLI mission and plays a key role here, setting the benchmark for data quality and coverage, proving what works today and guiding the technologies of tomorrow.
 
Its stability and precision are hallmarks of previous lessons learned, allowing scientists to trust the record across decades, and its success helps guide the innovations that will come next.
 
For more than half a century, Landsat satellites have given us an unbroken record of our changing planet.
 
In just four years, Landsat 9 has brought that vision into even sharper focus — capturing millions of scenes, advancing how we track water, ice, and land, and strengthening the world’s longest Earth-observation record.
 
It’s not just another satellite in orbit. It’s a bridge — carrying the Landsat legacy forward with enhanced technology while preparing the foundation for the future of sustainable land imaging.
 
Because with Landsat, every image is more than a picture — it’s a calibrated digital record, providing knowledge we can use to understand, protect, and sustain life on Earth.

Mars is not what it used to be. Once warm, watery, and blanketed by a thick atmosphere, today the Red Planet is cold, dry, and draped by a thin atmospheric veil.

The main culprit is a relentless stream of particles from the Sun, known as the solar wind. Over billions of years, the solar wind has stripped away much of the Martian atmosphere, causing the planet to cool and its surface water to evaporate.

Now, NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission, which launched on Nov. 13, 2025, has turned on the science instruments that will investigate how this happened and how the Sun continues to influence the Red Planet. The science instruments, which are all operating as of Feb. 25, also will study space weather in new ways near Earth and on the way to Mars.

At Mars, ESCAPADE’s findings could also help NASA protect future explorers from the harsh Martian conditions.

“The pioneering ESCAPADE duo will not only investigate the Sun’s role in transforming Mars into an uninhabitable planet, but also will help inform the development of space weather protocols for solar events directed at Mars during future human missions to the Red Planet,” said Joe Westlake, heliophysics division director at NASA Headquarters in Washington. “By joining the heliophysics fleet of missions across the solar system, ESCAPADE will be another weather station making humans and technology in space safer and more successful.”

First of its kind

With its twin spacecraft, ESCAPADE is the first science mission to coordinate two orbiters around Mars, gaining a perspective we’ve never had before. Together, the ESCAPADE twins will measure short-term changes in the magnetized environment around Mars, called the magnetosphere, and uncover real-time processes driving the planet’s atmospheric escape.

“Having two spacecraft is going to help us understand cause and effect — how the solar wind, when it comes to Mars, interacts with the magnetic field,” said Michele Cash, ESCAPADE program scientist at NASA Headquarters.

The ESCAPADE orbiters build on earlier Mars missions that have studied Mars’ atmosphere, but with just one spacecraft.

“The ESCAPADE mission is a game changer,” said Rob Lillis, the mission’s principal investigator at the University of California, Berkeley. “It gives us what you might call a stereo perspective — two different vantage points simultaneously.”

Once ESCAPADE reaches Mars, its twin spacecraft will follow each other in the same orbit, passing over the same areas at different times to uncover when and where changes are happening.

“When we have two spacecraft crossing those regions in quick succession, we can monitor how those regions vary on timescales as short as two minutes,” Lillis said. “This will allow us to make measurements we could never make before.”

After six months, the two spacecraft will shift into different orbits, with one traveling farther from Mars and the other staying closer to it. Planned to last for five months, this second formation aims to study the solar wind and Martian magnetosphere simultaneously, allowing scientists to investigate how Mars responds to the solar wind in real time.

“Prior spacecraft could either be in the upstream solar wind, or they could be close to the planet measuring its magnetosphere,” Lillis said, “but ESCAPADE allows us to be in two places at once and to simultaneously measure the cause and the effect.”

Preparing for human exploration

When people set foot on Mars, they will not be as well protected from solar radiation as their family and friends on Earth.

Earth can withstand the solar wind’s ceaseless onslaught because it has a hardy magnetic field that shields us from the Sun’s energetic particles. However, Mars’ once robust magnetic field has weakened over time. Today it’s a patchwork of localized magnetism in the planet’s crust along with an ever-changing magnetic field generated by the solar wind’s interaction with charged particles in Mars’ upper atmosphere.

This “hybrid” magnetosphere provides little protection against the atmosphere-stripping force of the solar wind. This, plus Mars’ thin atmosphere, allows the Sun’s energetic particles to easily reach the Martian surface, endangering future human explorers there.

“Before we send humans to Mars, we need to understand what type of environment these astronauts are going to encounter,” Cash said.

Additionally, ESCAPADE will provide more information about Mars’ ionosphere — part of the upper atmosphere that future astronauts will use to send radio and navigation signals around the planet, as we do on Earth.

“If we ever want GPS at Mars or long-distance communications, we need to understand the ionosphere,” Lillis said.

Unique journey to Mars

Previous Mars missions have launched when Earth and Mars are aligned in their orbits, which only happens every 26 months. But ESCAPADE launched early, pioneering a new strategy that allows Mars-bound spacecraft to launch almost anytime.

Instead of heading directly to Mars, ESCAPADE’s spacecraft are first looping around a location in space a million miles from Earth called Lagrange point 2. In November 2026, when Earth and Mars are aligned, the ESCAPADE spacecraft will return to Earth and use our planet’s gravity to slingshot themselves toward Mars for a September 2027 arrival.

This unique “loiter” orbit will extend approximately 2 million miles from our planet, making the ESCAPADE spacecraft the first to fly through a previously unexplored region of Earth’s distant magnetotail, part of Earth’s magnetosphere opposite the Sun.

“We’re going to be doing some discovery science,” Lillis said. “No one has ever measured Earth’s tail this far away.”

Later, during their 10-month cruise to Mars, ESCAPADE’s two spacecraft will study solar wind and the interplanetary magnetic environment that Mars-bound astronauts will also traverse, preparing for future journeys to the Red Planet.

The ESCAPADE mission is funded by NASA’s Heliophysics Division and is part of the NASA Small Innovative Missions for Planetary Exploration program. UC Berkeley’s Space Sciences Laboratory leads the mission with key partners Rocket Lab; NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Embry-Riddle Aeronautical University; Advanced Space; and Blue Origin.
